"Has this guys [sic] motives been questioned by the police department?" the post reads.

It turns out he has.

In response to the photo, which has been shared more than 400 times since it went live on Monday, Port Neches PD wrote:

"This person is well known to law enforcement. He lives in Nederland and comes to Port Neches as well. He has been arrested several times and has criminal trespass warnings at several local businesses. If you encounter this person and he displays a weapon in a threatening manner, call the Police immediately. He commonly carries a knife and displays a bizarre behavior..."

The comment goes on to say that the knife is legal and that law enforcement has tried to address his behavioral issues, but to little avail.

Southeast Texans have also chimed in with anecdotes of their own sightings of this unidentified man, with one Facebook user claiming the man has also been spotted walking around in his underwear or waving at people while sitting in a box.

And as is custom with Facebook posts, small arguments have broken out as to whether it's fair to pass judgement on someone who's not done anything illegal.

As one user put so eloquently, "Be careful not hateful just because he don't [sic] have an f250 with a Yeti sticker."
